Concanavalin A binding sites on the intestinal microvillus membrane of rat.
Concanavalin A binding sites on the intestinal microvillus membrane have been studied by means of Concanavalin A-horseradish peroxidase method. Several controls were carried out to demonstrate the specifity of this technique. Reaction product on the microvillus membrane of columnar cells on the upper bigger part of intestinal villi was found, while on the intestinal cells from the base of the villi and undifferentiated crypt cells no electron dense material was established. The results of the suggested method were discussed in relation with the literature data.
